SEA WIND POWER GENERATING FACILITY FOR MAKING INCLOSING NET}

The present invention relates to an offshore wind power plant, and more particularly, to an offshore wind power plant that constructs a cage farm that can reduce construction costs and create an environment suitable for fish farming through efficient use of materials.

Wind power is the most successful source of renewable energy. However, it is not easy to find a land for wind power generators in a country with a narrow country like Korea. Because of this, there is a growing interest in offshore wind power, with pillars in the sea and spinning windmills. The sea is also abundant in wind compared to the land, which is advantageous for power generation.

Wind power generation is a system that converts the kinetic energy of wind into mechanical energy using windmills and turns the generator to get power. Wind power facilities are divided into onshore wind farms and offshore wind farms installed on the coast or at sea.

The country with the largest number of wind turbines in Europe is Germany, producing 16,628 kWh (as of December 2004) from 16,6543 wind turbines. In Germany, more than 60 wind farms are currently in place.

It produces 100 kW of electricity. Germany accounts for 6.5% of the country's electricity demand. However, there is a shortage of places to install wind turbines inland, and attention is gradually shifting to offshore wind farms. Offshore wind farms are usually built on a large scale.

Recently, 15 countries around the world are planning offshore wind farms. To date, Western Europe is the main market, accounting for about 79% of the overall plan.

Wind power is clean energy with no emissions of environmental pollutants. For example, wind power generation produces 47,000 kWh of electricity annually, which can reduce 330 tons of sulfur dioxide, about 130 tons of nitrogen oxides, about 59,12 tons of carbon dioxide, about 8 tons of dust and about 41 tons of carbon monoxide.

Wind energy can be obtained from nature for free. Crude oil, reserve gas, coal and uranium, on the other hand, are limited resources. Wind power is safer than nuclear power. If the wind power plant is built, companies that produce or maintain components of the wind power generator can move into the complex, thus creating jobs.

However, the economic value of such offshore wind power generation need not be limited only to the generation of electricity, and furthermore, the offshore wind power facilities are developed into offshore spaces where the offshore wind power facilities are installed. You need to take advantage of it.

In order to meet this need, a technique has recently been proposed to construct caged farms using offshore wind facilities.

One such prior art is, for example, Patent No. 071438 (A cage farming method using an offshore wind farm structure).

The conventional technology is to form a cage farm by connecting the offshore wind power structure with a net, only the concept is shown, and practical technology has not been proposed.

In addition, there is a patent No. 0848840 (a cage farm using offshore wind power facilities).

The prior art includes a plurality of foundations constructed from the bottom of the seabed, a road of concrete constructed from the bottom of the seabed between the foundations, and a mesh portion installed on the roads. There is a problem in that the construction cost is very large because it requires concrete.

And, since the road is built at a certain height from the bottom of the seabed, and the mesh part is installed on the road, the farm is made by the road and the mesh part, and as much of the farm is made of concrete structures (roads), There is also a problem that aquaculture farms are contaminated, resulting in poor efficiency.

In addition, there is a problem that requires a separate drainage means for draining the water in the farm because the road constitutes a farm.

In addition, the road is built from the bottom of the seabed to the height between the highest and lowest water level is locked in the water at the time of the highest level, there is also a problem that can not be used as a road.

In addition, the underground line portion for transmitting electric power generated by the wind power generation facility is installed on the road, the road is locked in the water, so there is a problem that a lot of restrictions occur in the repair work, such as cable.

The present invention is to solve the problems described above, it is possible to efficiently secure the amount of power generation by using the abundant wind of the sea, and to form a cage farm using a wind power plant, but requires a large amount, such as concrete The objective is to provide offshore wind farms that can produce cages without using materials.

The foundation support pile 20 can be installed on the sea and can be made of all materials and structures that are not deformed and damaged by salts and waves of the seawater, and can also support the foundation 10 while maintaining the state standing on the sea. Quantity and all construction methods are possible.

The foundation portion 10 is constructed by field casting or precast on the foundation support pile 20, the generator is mounted therein, the cable is wired, and the cable box 40 is wired inside the cable box 40. ).

Wind power generation means 30 includes a windmill, a generator for generating the rotational energy of the windmill as electric power, which will be practiced by those skilled in the art because it uses a well-known, and will not be described in detail.

The base 10 has a function of constituting the farming section 200 while supporting the wind power generation unit 100, and is arranged in a polygonal polygon or more to form a space that is blocked from the outside when viewed in plan.

As shown in Figure 3, the cable box 40 is composed of a box body 41 hollow inside so that the cable 31 of the wind turbine 30 is wired. That is, the cable box 40 refers to a function of wiring a cable, a function of a check road for checking the cable, and a function of a road through an upper surface.

The box body 41 is constructed to be in contact with the base 10 between the adjacent bases 10 so that the cable 31 is wired from the base 10, for example, the base 10. Inside the tube of the wind power generation unit 100, the tube is wired may be embedded, the cable may be wired in the cable box 40 through the tube.
